Test Servers.

To gauge the quality of a user's broadband connection, the SamKnows measurement agents need to measure network performance from the user's home to a measurement target on the internet, and vice versa. We call these measurement targets "test servers". SamKnows maintains a variety of high-capacity test servers across the globe for precisely this purpose, and ISPs are able to deploy their own test servers within their network for use as additional test targets.
